'As indicated in the shed.

end controller constituted as a part-er and The lay 5 may be operated asusual from clamp Which on call for replenishment is thecrank shaft'andat its outer endcarries moved rearwardly towards the shuttle box I thereplenishing shuttle box 6, and the shuttle to position the parter andclamp for parting 7 may be of usual type of filling replenishing andclamping the filling end close to the shuttles nowwell-known in theart.,

The front shuttle box plate is provided which divides the front boxplate into the anchoring member 9 and the shorter upper member 10 whichis secured to the anchoring member 9 at the outer portion thereof, as at11, and is solely supported by the anchoring member.

The lower flange portion of the anchoring member may be secured to thelay by bolts 12 and 13 which extend through slotted lugs 14 formed inthe flange of the anchoring member, with the result that while theanchoring member is rigidly secured in position, the shorter uppermember 10, being supported solely at the outer portion of the anchoringmember, may yield to some degree, and as the shuttle enters thereplenishing shuttle box the inner face portion of the an choring memberwill first engage the shuttle and resist the first impact, andthereafter the shorter upper member will act upon the shuttle as itmoves to picking position in the shuttle box.

Between the inner end of the anchoring member and the inner end of theshorter upper member of the front box plate there is a free andunobstructed opening which not only provides an open inner end for thefront box plate but likewise presents a space into which the spentfilling end may be thrown as the shuttle comes to rest.

At the inner end of the anchoring member 9 is a projection constitutinga spent end catcher 15 which extends frontwardly and below the level ofthe lay end A notch or hook is formed at the top portion of theprojection tov catch the incoming filling end should it tend to slide bythe top of the box plate into the shuttle box.

When the spent filling end is withdrawn from the shuttle box, ashereinafter descirbed, it is held in front position for several picks oruntil the temple thread cutter parts it at the selvage, but should thespent filling end be broken by catching on some of the lay parts beforeit is cut at the cloth selvage, the loose end would probably be drawninto the shed. The thread catcher of the present invention, however,avoids this objection by holding the spent filling end, which is givena. certain amount of slack between the 'cloth selvage and the threadparter and clamp, as will appear, so that it is prevented from catchingon any part of the lay or shuttle box during lay movements.

Secured to the hopper or magazine stand is a stud shaft 16 on which ismounted the transferrer 17 normally under the influence of a spring 18,as usual, for maintaining the transferrer in its upper or inoperativeposition.

Extending downwardly from the hub of the transferrer is an arm 19 towhich is pivotally connected at 20 the usual dog 21, and ex tending fromthe dog 21 is a stud 22 which engages the slotted arm 23 mounted forpivotal movement about the axis 24: on call forreplenishment of filling,the result being that on rocking movement of the shaft 24: the dog 21will be raised into the path of the usual bunter 25 on the lay, wherebythe transferrer is operated to transfer a fresh filling carrier to theshuttle and eject the spent filling carrier or bobbin therein.

Mounted on the transferrer stud 16 at the outer end portion thereof is abracket, the hub portion 26 of which is secured to the stud shaft 16,and extending downwardly from the hub are the arms 27 and 28 which arearranged in a vertical plane inclined rearwardly towards the outer endof the shuttle in the replenishing box.

The arms 27 and 28, being positioned as described, carry the guide 29for a slide 30 which has a movement towards and from the front of theloom in an inclined path diverging outgvardly towards the outer end ofthe shuttle The inclined slide 30 has a laterally projecting portion 31,Fig. 3, and upon which is mounted the thread controller constituted as athread parter and clamp having the usual cutting and clamping members.The fixed cutting member is indicated at 32 and the fixed clampingmember at 33, while between the two is the movable cutting member 3 1and the movable clamping member 35, which are pivoted to the projectinglug 31 as at 36, and a pin 37 connected to the movable cutting "andparting members serves to actuate them as will more fully appear.

Mounted upon the transferrer stud 16 for rocking movement is the yoke 38having the arms 39 and 40 which swing about the transferrer stud. Thearm 10 is extended downwardly and is provided with a slot 41 at itslower end portion which engages arelat-ively long pin 42 extendinglaterally from the slide 30, as indicated more clearly in Fig. 3. The

arm 40 which constitutes an actuator for the slide moves or swings in avertical plane (:1 tending at right angles to the lay, while the slide30 which is actuated by the arm 40 moves from front to rear position inan inclined path to part and clamp the filling, and as the actuatorswings frontwardly in the vertical plane of its movement the slide 30moves frontwardly 1n an 1ncl1ned direction towards the cloth selvage orinner end of the shuttle box, with the result that on call forreplenishment of filling, as will later appear, the actuator and thethread parter and clamp will cause the spent filling end to be withdrawnfrontwardly from the shuttle box to provide slack between the parter andclamp and the cloth selvage so that the slack spent filling end mayengage beneath the thread catcher 15 as the lay again moves frontwardlyand thereafter the filling end will be prevented arm 23, and since theshaft 24 is rocked on call for-replenishment of filling theactuator 40will be moved rearwardly to position the thread parter and clamp'to partand clamp the thread adjacent the shuttle eye, and when the shaft 24;rocks in the opposite direction after replenishment, the actuator'willagain be moved frontwardly in its plane of movement to withdraw theslide 30 and the thread parter and clamp frontwardly in an inclined pathtowards the inner end of the shuttle box.

Should the spent filling end be unprovided with slack as it is drawnfrontwardly from.

the shuttle box it is liable to catch upon the upper portion of theanchoring member 9 of the front box plate or upon the stud 13 whichsecures the anchoring member to the lay, but

by providing slack in the spent filling end as it is withdrawn from theshuttle in the inclined path described, the spent filling end willengage beneath the catcher 15 and be thereafter held from moving intothe path of the shuttle or the air currents produced thereby. p

Mounted upon the transferrer stud 16 is a second yoke 47 mountedfor-rocking movement, and extending towards the inner end of the shuttlebox is the arm 48 secured to.

the yoke and likewise connected by a yielding member 49 to a stud 50 onthe downwardly extending arm 19 of the transferrer. Connected to theouter end of the yoke .47 is an arm 51 in which is adjustably'mounted aparter and clamp closing member 52 which,

when the parter and clamp are in rearward position, 7 V and clamp topart andclamp the spent acts upon the pin 37 ofthe parter It is.desirable'that the clamped end of the spent filling be held by theparter and clamp until the next call for replenishment offilling, and inorder to open the parter and clamp as they move to rear positionasdescribed, there is a tr p opener 53 of usual construction and supportedfor rocking movement freely in one direction to act upon the pm 37 andcause separation of the parter and clamping members as they move torearward position.

As the parter and clamp move to rearward position to part and clamp thespent filling end, it is desirable that they should be properlypositioned in the enlarged opening 54 in the front box plate, and tothis end the slide 80, which as above described, moves in an inclineddirection rearwardly. towards the outer end of the shuttle box and thenfrontwardly towards the cloth selvage or inner end of the shuttle box,is provided with a hunter 55 which may engage a part carried by thelay-and properly position the parter and clamp for their parting andclamping operations.

The movement of the parter and clamp, the hunter and the slide .30carrying these parts, is indicated by dotted lines in Fig. 1, wherein itwill be noted that the parts cited move from their full linepositionrearward- .ly towards the outer end of the shuttle box on callfor replenishment of filling and then return in an inclined path towardsthe inner end of the shuttle box as they move to outer position,thereby. producing slack in the spent filling end.
